Dynamical time division duplex uplink and downlink configuration in a communications network

An apparatus of a user equipment (UE) operable to reconfigure a time division duplex (TDD) uplink and downlink configuration, the apparatus comprising one or more processors and memory configured to:

• process, at the UE, an uplink and downlink (UL/DL) configuration indication received from the eNB for the TDD reconfiguration, the UL/DL configuration indication comprising:
• a set of configuration indication fields numbered 1 to N, included in a downlink control information (DCI) format Y carried on a physical downlink control channel (PDCCH), where
• N
• =
• ⌊
• L
• format
• ⁢
• ⁢
• Y
• M
• ⌋
• ,
• Lformat Y is equal to a payload size of the DCI format Y, and M is a number of bits of each indication field;
• and
• decode, at the UE, an encoded PDCCH received from the eNB, wherein the DCI format Y is mapped onto the PDCCH, wherein the PDCCH is encoded with a cyclic redundancy check (CRC) scrambled with an enhanced interference mitigation and traffic adaptation (eIMTA) Radio-Network Temporary Identifier (RNTI) for the UE.

At least one non-transitory machine readable storage medium having instructions embodied thereon for modifying an uplink/ downlink (UL/DL) configuration at a user equipment (UE) in a communications network, the instructions when executed perform the following:

• requesting, using one or more processors at the UE, a radio resource control (RRC) connection with an eNodeB;
• signaling, using the one or more processors at the UE, a UE Capability Information information element (IE) for transmission to the eNodeB, wherein the UE Capability IE indicates an enhanced interference mitigation and traffic adaptation (eIMTA) capability of the UE to support an eIMTA time duplex domain (TDD) UL/DL reconfiguration functionality;
• and
• processing, using the one or more processors at the UE, eIMTA configuration information received from the eNodeB via a radio resource control (RRC) message, wherein the eIMTA configuration information is received in response to signaling the UE Capability IE to the eNodeB.
